HOT-WATER BOTTLE.

Application filed March 18, 1926. Serial No. 95,682.

The present invention relates'to hotwater bottles which are rubber bags having on one edge an apertured tab by which the bag may be hung in a reversed position so as to drain and having on the opposite edge a mouth provided with an integral tab by which the bag may be held while it is being filled. After the bag has been filled the mouth is closed by a separable stopper.

The mouth tab, owing to its size,'must be held between the thumb and forefinger while the bag is being filled. Because its surface is smooth and slippery, particularly when wet, the tab is hard to hold under the increasing weight of the hot water poured into the bottle. The fingers holding the tab are close to the stream of hot water entering the bottle and are liable to have hot water spatter on them resulting in a loosening of the grip on the slippery tab. The separable stopper for closing the mouth of the bottle often becomes mislaid or drops from the hand into a position from which it is recovered with difiiculty just when it is needed to seal the mouth of the filled bottle.

The object of the present invention is to produce a hot-water bottle in which the stopper is always available for use both as a seal and as a reliable gripping device for the hand in the bottle-filling operation.

To the accomplishment of this object, and such others as may hereinafter appear, the features of the present invention contemplate the provision of certain devices, combinations and arrangements of parts fully set forth hereinafter, the advantages of which will be readily understood by those skilled in the art. The various features of the present invention will be readily understood from an inspection of the accompanying drawings illustrating the best form of the invention at present known to the inventor, in which- Figure 1 is a front elevation of a hotwater bottle, 7

Fig. 2 is a detail in side elevation, and

Fig. 3 is a detail sectional elevation.

The hot-water bottle 4, ordinarily made of rubber, is provided on its bottom edge with an apertured tab 5 by which the bottle may be hung in a reversed position to drain. On its upper edge the bottle is provided with a mouth 6 having a peripheral lip and an apertured tab 7 integral therewith and forming an extension thereof. i

The mouth 6 is closed by a threaded stopper 8 which fits into a threaded sleeve 9 (F 1g. The stopper 8 is provided with an operating handle having a large head 10 and a small'shank 11. The walls of the aperture in the tab 7 are elastic to permit them to expand and allow the passage of the head 10 through the aperture and to contract, after the passage of the head, to cause tiliem to grip in a yielding manner the shank With this construction the stopper 8 affords an effective gripping device for preventing the bottle slipping from the hand during the bottle-filling operation. After the bottle has been filled the tab 7 may be bent within the mouth of the bottle (Fig. 3) and the stopper 8 rotated into the sleeve 9 to seal the bottle. The shank 11 of the stopper is yieldingly engaged at all times by the elastic walls of the aperture in the tab 7 so that the stopper cannot become mislaid or drop from the bottle at inconvenient times.

What is claimed asnew, is:

A hot water bottle having, in combination, a mouth having a peripheral lip, a stopper for closing the mouth, provided with an operating handle having a large head and a small shank and a tab integral with the mouth and forming an extension of the lip and having an aperture therein the walls of which are elastic to permit them to expand to receive the head and to contract to engage the shank and yieldingly support the stopper for rotative movement.

In testimony whereof I have signed my name to this specification.
